First it was the feds telling us that they will detect terrorism by examining our frown, nose, eyebrows, jaw thrusts, and forehead scrunch.

The “secret sauce is software that detects ‘high frequency vowel sounds [that] span a broader frequency range.’”

Aggressive people tend to tense their larynx, and the sound made by their vocal cords is distorted… A truly aggressive voice is very hard to imitate.”
